feat(output): rsync 3.4.1 selection and output parity (#291, #292)

#291:
- Compile --exclude/--include/--exclude-from/--include-from into the SAME
  ordered rule list as --filter/-f (first match wins), so the common
  `--include='*.txt' --exclude='*'` idiom and include-alone semantics match
  rsync. The legacy per-kind scanner arrays are no longer applied.
- -x/--one-file-system emits the cross-device mount-point directory entry
  (empty) instead of dropping it, in both the sequential and parallel scanners.
- Stop passing the legacy arrays to the scanner; document -f is --filter.

#292:
- New src/shared/format.c/.h: rsync "big_num" (comma-grouped integers) and
  decimal -h human sizes, %M/%t timestamp, and the STATUS_DEST_INFO codec.
- Receiver answers each STATUS_CHECK with a pre-transfer destination snapshot
  (new report_dest_info wire field + STATUS_DEST_INFO, PROTOCOL_VERSION
  2.23.0) so the sender can render true itemize columns.
- Itemize now emits rsync-correct update/type chars and c/s/t/p/o/g columns
  for files, dirs, symlinks and hard links, comparing size/time/perms/owner/
  group against the reported destination.
- --out-format gains %i %n %f %l %b %M %t %o %p %B %U %G %L; %f is the
  relative display path, %M the YYYY/MM/DD-HH:MM:SS form, %b the literal
  bytes sent.
- --list-only prints transfer-relative names, directory entries and ls-style
  grouped sizes.
- --stats prints rsync's multi-line block on stdout; -h uses decimal units.

Tests: unit tests for the filter ordering, format primitives, itemize
columns; integration + differential tests against real rsync 3.4.1 for
itemize/out-format/list-only/selection and -x. Golden wire len/hash and
protocol version strings updated for 2.23.0.
